The Covid-19 pandemic increased general awareness of the importance of fresh outdoor air delivered to occupied spaces. Zones that use Variable Air Volume (VAV) boxes for heating and cooling loads can also be used for ventilation. However, when using other zone control systems for temperature control, such as Variable Refrigerant Flow (VRF), another system must […]

With increased energy costs and mandates from government agencies to reduce carbon emissions, it is becoming more essential to accurately measure and monitor thermal consumption within buildings. There is an upward trend in many facilities installing thermal energy meters (BTU meters) in commercial/multi-tenant energy metering, and monitoring applications such as retail units, condominiums, apartments, or

Super capacitors (SuperCaps) are electrochemical condensers that are faster in response and more reliable than conventional rechargeable batteries. This modern energy storage technology is advancing energy efficiency and the functionality of complex safety solutions around the globe. Belimo has intensively tested and improved the SuperCap technology to equip damper and valve actuators with an innovative electronic

According to the Organization for Economic Cooperation and Development, and as reported by EdWeek, the average U.S. student spends 8,884 hours over nine years in primary and lower secondary education. Recent research has shown that poor air quality can negatively affect health and academic performance. With students spending around 1,000 hours a year in classrooms,

Fire and smoke dampers are essential to a facility’s overall fire and life safety protection system. Unfortunately, dampers tend to fail during routine inspections frequently. It may not seem a big deal, especially with other fire protection features (fire doors, fire stopping). Fire and smoke can spread fast, and one of the quickest ways for

“The buildings sector accounts for about 76% of electricity use and 40% of all U. S. primary energy use and associated greenhouse gas (GHG) emissions, making it essential to reduce energy consumption in buildings in order to meet national energy and environmental challenges (Chapter 1) and to reduce costs to building owners and tenants.” To

Belimo devices can be found in a wide range of building applications across the globe – silently and reliably helping to improve occupant comfort and reduce energy consumption through HVAC system optimization. In recent years, advancements in IoT and digitalization have allowed these devices to become “smarter” by generating valuable data that can be used

When designing commercial HVAC damper applications, many factors are considered that impact actuator selection. Every actuator manufacturer has an applied torque limit to consider. When factoring in the controllability of a damper, the control system is simply sending a control signal to “an actuator” to drive “a damper.” The control signal is not affected that

Often times, the question of “Do I really need a control valve?” arises when tasked with engineering an application which involves controlling a process. These control applications may vary in pressure, temperature, flow, conductivity, pH, etc. As such, traditional wisdom would have us pulling out our good old “control valve” books to find a solution.

From industrial gas lines to household appliances, from wastewater treatment to pharmaceutical processing, from fuel pumps to air compressors, the functionality of check valves remains diverse, running the gamut through a myriad of liquid, gas, and slurry applications. Though check valves appear in a variety of forms, the fundamental premise of these units remains similar:
